SPECIFICATION forming part of Letters Patent No. 657,482, dated September 4, 1900. Application filed May 26, 1900. Serial No. 18,170. (No model.)

T0 at whom it may concern.-

Be it known that we, WILLIAM J. COX and SERVETUS O. GRAY, citizens of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Lubricators and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to lubricators, and more particularly to that class of lubricators designed for greasing traction-rails at curves to permit a street-car to more easily'round the curve;

The object of the invention is to provide a device of this character which shall be under the complete control of the motorman or gripman, who upon approaching the curve may move the discharge end of the lubricator into contact with the inner side of the wheelfiange, which will distribute the lubricant upon the guard-rail at the curve.

With this object in view the invention consists in certain features. of construction and combination of parts, which will be hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view of the front portion of a streetcar, illustrating the application of our invention, and Fig. 2 is a bottom plan view. Fig. 3 is a longitudinal sectional view through the grease-box. Fig. at is a bottom plan view of the box.

Referring to said drawings, 1 denotes the platform of a street-car, and 2 the front wheelsthereof.

3 denotes the grease-box, provided with a removable cover 4 and a tapering outer end 5.. One side of the grease-box and tapering-end are flat and provided with guide-strips 6. In

the flat side of the tapering end of the greasebox is formed a discharge-orifice 7.

8 denotes a discharge-tube, one side of which is flat and is provided with an aper-. ture 9 and with a bar 10, which is adapted to slide between the guide-strips and is connected at its inner end to the inner end of the grease-box by a coil-spring 11, which exerts its energy to draw the discharge-tube inwardly, so that its orifice will be unalined with the orifice in the outer end of the grease box. The extreme outer end of the dischargetube is secured to a brush-head 12, which is provided with a central discharge-apex ture 13. r

14 denotes a removable springactuated plunger located in the grease-box and connected to the removable cover and serves to force the lubricant, which is in a semifluid condition or in the form of paste, through the discharge-opening 7 in the outer end of said box.

15 denotes a cam journaled to the fiat side of the grease-box and provided with an enlargement 16, which is adapted to be moved into engagement with the inner end of the discharge-tube and force the same outwardly, so as to aline its opening with the opening in the outer end of the grease-box. A spring 17 is connected tothe cam and serves to restore it to its normal position. To check the rotation of the cam and to prevent its enlargement being moved beyond the inner end of the discharge-tube in the act of depressing it, I provide the periphery of the cam with a stud 18, which is adapted to engage a fixed stop 19, secured to the side of the box.

Any suitable means may be provided for rotatin g the cam; but those shown in the drawings are preferred and consist of a crankwheel 20, the crank 21 of which is connected to a crank 22 of the cam by a link 23. A pushrod 24 is pivoted to the crank-wheel and extends up through the platform of the car and is within convenient reach of the motormans foot.

In operation in approaching a curve if it be desired to lubricate the guard-rails thereof the push-rod is depressed by the motorman. This through the intermediate mechanism alines the aperture of the discharge-tube with the aperture in the outer end of the greasebox, and the grease within said box being under pressure of the spring-actuated plunger is forced through the alined apertures and out through and between the fibers of the brush-head. In the act of alining the two apertures the discharge-tube is forced outward, with the brush-head in engagement with the inner side of the wheel-flange, so that the grease is discharged directly upon the flange of the wheel and will be distributed upon the without requiring an extended explanation The device is exceedingly useful'for the purpose for which it is designed and may be placed upon the market at a comparatively; small cost.

Various changes in the form, proport2i'on;'

and the minor details of construction may be resorted to without departing'fr'omtheprim ciple or sacrificing any'of' the-advantages of this invention. I v

Having thus-fully described our invention,

Letters Patent of the'United States; is-' the combin ation with the grease-box provided with a. discharge-opening, of a movable-'idis charge-tube connected to the greases-box and provided with an opening, and means feral-in ingthe two openings to permit of the dischargeof thelubricant from the grease-boxinitoand through the discharge-tube,substantially as set forth.

2. In a lubricator of the character described, the combination with'the greasefbox provided thecombinatiomwith the, grease-box provid ed with-a discharge-opening of adis'charge-tube connected to said grease-box and provided with an opening, means for normally holding "the openings in unalined relation, and means for moving the discharge-tube 100 aline said openings -and-permit of-the dischargeof the lubricant through said openings, substantially as set forth. v
